Abstract (en)
[origin: WO2022129140A1] The invention relates to a process for producing hydrophilically modified polyisocyanates having a very low content in monomeric diisocyanates, the polyisocyanates obtainable or obtained according to the process and the use thereof for producing polyurethane plastics. The invention further relates to coating agents that contain the non-ionic hydrophilically modified polyisocyanates and to the substrates coated with said coating agents.
